正如@Loathing评论的那样， BindingList 也为我工作。它将如何工作：

As @Loathing commented BindingList worked for me too. How it will work :

BindingList<ioChannel> myList = new BindingList<ioChannel>();
dgvChannels.DataSource = myList;

BindingList具有通知列表更改的事件。以便datagridview可以通知自己重绘，检查这个。有关更多信息，请访问 msdn 。

BindingList has event that notifies changes in list. So that datagridview can notified to redraw itself, check this. For more information visit msdn.
